To all whom it may concern:

7 Be it known that I, Winn/tea J. Winona, a citizen of-the United Stateresiding at New York,county of New York, and rotate of New York, haveinvented certain new and Automatic St-o for litaihvay-Train'af ful y ingMechanism,

mentsin automatic stopping mechanism i501- railwa trains.

lnt e-.o oration of rdilwave, and articularl in t operation ofelectrical y operat railways, on which high apeed and fre- 4 wentservice, are maintaingd, it is desirable t at the'trams be provided withstopping. devices which aha] operate to prevent a train'trom using asignal which in in atop positiomt will be which shall be of such acharacter as to prevent. the driver of a train from runnin? by a mi nalwhich is set against him wttiuut hia eing apprised of that fact.

A further objet-t'of-the invention is to produce an improved automaticstopping mechamsm for .rallroadtrams which shall be 01' such a characterthat the driver of the train is prevented from runningby a signal whichis set against him without being apprised of that fact but which alsoenables him to pass such a signal if the conditions render:

. unnecessary.

The invention further extends to certain improvements in details ofconstruction by which the objects referred to are carried into efl'cct.

It will-be understood that the rilnary function ofthis 5 conductor is to supp y the current which furniahcs the tubtivemwer for the motors of thetrains,*wh ere t to invention is employed,

in connection with electrically o 'ierat ul trains. Anelectric-locomotive or car is indicated at 8, said locomotive or carbeing;

represented as attached to other cats, indicated at 4.

- ln'what are regarded as the best construe-t 'tions for carrying theinvention into eflect, the working-conductor will embody what may betermed a controlling section of short length, "this section beingindicated at 5.

. The purpose of this section is to control,

through proper agencies, the stopping devices on the car, locomotive ort-rain,.ut the time a signal inset against the driver-of the tram, andwhile the lcngtlrot' the controlling scction may be varied, it shouldnot be longer than the length of a train, and, in thebest forms ofconstructions, it will be less in length than an ordinary car; it beingunderstood that the term car as used III the specification, is meant toinclude any form of car or locomotive. In the best conso structionsembodying the invention means will be employed for rendering thiscontrolling-section operative or inoperative :with. respect 'to thestopping devices to be hereinafter described, and these means are,

38 in the construction ilhhtrated, of such a character-as-to becontrolled from the signal employed. According to one form ofconstructicn illustrated (see Fig. 2) this controlling scction is madeinoperative by 0 5 its position. When the invention is come into eilectby a construction in which the controlling section is made inoperativeby change of position, the conttnuit of the working conductor maystanding thistchange in position bvsuitahle connections.
